Abstract

The solubilities of oxygen in pure water and in aqueous solutions containing NaCl, (NH₄)₂SO₄ or sucrose were determined at 25°C by using a saturation method. Those in the aqueous solutions NaCl+(NH₄)₂SO₄. NaCl+sucrose and (NH₄)₂SO₄+sucrose, which are key components of fermentation media, were also measured. The results obtained were correlated by the equation of Sechenov. Oxygen solubilities in aqueous solutions containing a single salt or sucrose were well represented by modified salting-out parameters of ammonium ion and sucrose. Those in aqueous solutions containing mixed components could be predicted by using the salting-out parameters of single salt and sucrose based on the linear relationship proposed by Danckwerts.
